General Description

(-)-ESPHOS LIGAND is a chemical compound with a purity of 98+%. It is commonly used as a ligand in transition metal-catalyzed asymmetric transformations. (-)-ESPHOS LIGAND is known for its ability to stabilize metal complexes and facilitate chiral induction, making it a valuable tool in organic synthesis. It has been utilized in a variety of reactions, including the asymmetric hydrogenation of ketones and imines, as well as the allylic alkylation and arylation of alkenes. (-)-ESPHOS LIGAND, 98+% is an important component in the development of efficient and selective catalytic processes in organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 254990-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,9,9 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 254990-08:
(8*2)+(7*5)+(6*4)+(5*9)+(4*9)+(3*0)+(2*0)+(1*8)=164
164 % 10 = 4
So 254990-08-4 is a valid CAS Registry Number.
